- rmn-acruarrnn ELECTRIC V SWITCH.

. Application filed December 10,1921; Serial a... 74,5215.

,This invention relates to electric switches and has more particular reference to atime control means for actuating t e switch for closing an electric circuit to electric lighting means.

The primary ob'ect of my deviceis to provide aswitch 0 this character that may be installed as a unit, preferably within a hen house, in order that the electric lights may be turned on prior to the days sunrise so that artificial light will be provided for rousing the hens in order that they will be- 1 gm laying thus producing a supply of eggs prior to sunrise;

A further and important object is to provide a time controlling switch mehanism that may be associated with the well known type of electric switch, which will be so associated with the time controlled mechanism as to provide a complete unit within'itself, that may as above'stated, be readily'set up in a hen house or the'like.

A still further object is to substantially improve and simplify over previously pat ented and used devices of this character.

With the foregoing and other objects in view as the, nature of the invention will be better understood, the-same comprises the disposed.

novel form, combination and'arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing wherein like reference characters indicate corresponding parts throughout the several views:

Figure 2 is a. similar view disclosing the internal mechanism thereof, and

'Figure 3' is a detail sectlon' disclosing the preferred manner of-association of one member of the switch control mechanism with 'drawing, my novel mechanism constitutes the provision of a box-like casing 5, disosed upon a base board 6 that may read- 11y secured to the floor or wall of a hen house, or other building wherein the same is Located within the casing 5 is' a well known type of electric snap switch 7 to the 5 positive and negative contacts of which are l 554 electrically connected ends of cables Sthat are in electric circuit with one or more elecallcl'relation with-the cloc Figure 1 is an exterior elevation of theunit.

tric lights as wellas .a' source of electric power, said cables extending through suit-. ablepopenings' in the casing, as is shown in Figure2. 1

-'lhe"front wall of the casing 5 is formed withan opening within which is rigidly disposed a conventional form of 'alarm clock 9,-- the-outer face of which isexteriorly of the casing, while the inner face thereof is within.- the gasing as clearly shown in Figures 1 and Q 1 In carrying out my invention I remove the usual winding means from the clock alarm winding shaft A, which is screw threaded as shown in Figure 3, I then thread upon this shaft .an internally threaded sleeve 10 that isxforl'ned 'upon the inner end of a rod 11 at right angles thereto. Said rod extends outwardl in spaced, par- 11 and is pivoted at its outemend as at 12 to the lower end of a connecting rod l3, which rod extends upwardly and it is in turn pivoted at its -opposite end asat 14 to an arm 15, in general parallel relationiwith the rod 7 The inner end of this arm is so constructed as to provide a clamping'means whereby the same may be rigidly connected to the usual thumb button B, of the switch 7.

Connected to the rod 11 intermediatethe .ends thereof is one end of a retractile coil spring 16, the other end of which is secured through the medium of a hook tothe wall of the casing upon which is disposed said.

switch 7 I 4 In the: position of the structural elementas shown in Figure 2, the switch 7 ,is in ofiposition. Obviously, after the alarmmechanismhas been set to go off at a pre-;

I determined time, the winding shaft A will be. released when this time is'reached, and through the medium of the sprin '16 the rod 11 will bethrown upwardly int e direction of the arrows, Figure 2, for then moving upwardly upon the rod 13 and consequently the arm 15 which will move the button of the switch to closed position, and consequently permitfthe current "to flow to the.

'hghting l eans. v T

When it is desired to switch off the lights and rest the device, it. isonly necessary that .the rod 13' be grasped and then forced downwardly for again moving theelements'to the position, shown in Figure 2 where they will be so maintainedv until the set time has again beenreached. v w

may be readily set up in hen houses or the like as a unit, and wherein the construction.

of the same is of such a simple nature as to not readily become out of order, and that may be manufactured and marketed at low cost.

Minor changes may be. made in the inven-' tion without departing from the spirit and scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is I In combination, a casing, an electric snap switch located within the casing, analarm clock arranged within the casing, a rod, an internally threaded sleeve formed on the inner end thereof and disposed at right angles thereto, said sleeve being adapted for secured at one end to the outer end ofthe first mentioned rod, the other end being securedto the outer end of said arm so that said arm will be moved to a switch actuated position when the 'first mentioned rod is operated by reason of the alarm winding shaft being released, and a retractile coil spring being secured at one end to the intermediate portion of the first mentioned rod, and at its opposite end to the casing, for immediately so moving they arm to a switch closing position when the alarm winding shaft is released.-

In testimony whereof I aflix my signature.-
